In Ballz, the idea is to break as many bricks as you can before they touch the ground. You have to know your angles, collect extra balls, and and try to beat the high scores. You can also spend rings to begin with extra balls.

Looks like a typical iOS game that gets repetitive and boring real quick.

Yep, longevity is a worry but as a blast for a bank holiday weekend it's been fun so far. I also saw a video that had players scoring over 800 rows and I'm only on 123 so let's see. But even if I get bored of it tomorrow it's still been fun along the way.

It gets boring quick, as its a free to play game (you can unlock it for a small fee), you are constantly restarting after being fed an advert, which means you are playing the weak start then ramp up over and over.
Look tis harmless, stella likes it, I'm not going to rag on him or call for a jihad or anything but like elf I'm just getting a bit bored of these things now.

Anyone who likes this should check out Charming Runes. Pretty much the same thing but with more depth and more IAP stuff but not too intrusive. Made by people connected to Crossy Road people.
Not sure what came out first Runes or Ballz

Have you had a look at Charming Runes? There's more sense of accomplishment in that. I'm up to 180 in a paused game and I find that it doesn't really get any harder or easier the further you get in, you just try to do the same thing each move really.
